When I was first introduced to the idea of clipboard managers, I tried a half dozen or more of them before deciding to use ClipX. Every time since then when I’ve heard of a new one, I’ve tried it out and returned to ClipX. The one major drawback is it hasn’t been updated since 2008 (I’m using the 64-bit beta version), but so far I haven’t needed any updates. I don’t know when I’ll move to Windows 8, but as long as ClipX keeps working, I don’t plan to switch.
